Muscle Tissue
Characteristics
- 1. Elongated shape, longer than rounder
- 2. Myofibris contain actin and myoson (rods) MUSCLE
-
Three types of Muscle Tissue
- 1. Skeletal Muscle- movment of the skeleton
- 2. Cardiac Muscle- the heart
- 3. Smooth Muscle - walls of hollow organs
-
Muscle Tissue
Skeletal Muscle
- 1. Voluntary
- 2. Straited muscle
- 3. Long cells
- 4. each cell as long as muscle
- 5. many nuclei
- 6. each has a this layer of CT with fibrobasts that resemble nuclei
-
Muscle Tissue
Cardiac Muscle
- 1. LIghtly striated
- 2. single nuceius
- 3. INVOLUNTARY
-
Muscle Tissue
Smooth Muscle
- 1. Involuntary
- 2. If it's not the heart and doesn't move body it is ....
- 3. eye, stomache, wall intestines
- 4.NO STRIATIONS
- 5. Spindal shape cells
- 6. More nuclei than reg CT
-
Nervous Tissue
Brain, spinal cord, all peripheral nerves
-
Nervous Tissue two different cell types
-
Nervous Tissue
NNeuron cell type
- 1. also called nerve cells
- 2. do not under go mitosis
- 3. decrease as we age
-
Nervous Tissue
Neuroglia
- 1. supporting cells
- 2. undergo mitosis
- 3. cancer in the brain comes from these guys
- 4. Help protect and support nervous tissue
- 5. Insulate electrical
